Application tiled March 1, 1913. Serial N0. 751,473.

To all whom it may concern:

Be it known that I, JOSEPH Mazen, a citizen of the United States, andresident of McAlester, in the county of Pittsburg and State of Oklahoma,have invented a new and useful Improvement in Vindin -Indicators; and Ido hereby declare the ollowing to be a full, clear, and exactdescription thereof.

My invention relates to winding indicator mechanism for watches,graphophones or other devices, which shows to what extent the device hasrun down and when it needs winding up.

The object of the yinvention is to provide a simple and effective formof mechanism for this purpose which can be located in the ordinary watchmovement (when it is applied to a watch) without increasing the size oi'the space required for such move.- ment and without the necessity ofchanging materially the standard construction.

i To these ends my invention comprises the novel features hereinafterset forth.

In the accompanying drawing Figure 1 is a face view of a watch with myinvention applied thereto; Fig. 2 is an enlarged fa e view with the dialremoved; Fig. 3 shows the reverse side of the watch showing crown wheeland ratchet; Fig. 4 is a cross section on the line 4-4 Fig. 2; Fig. isan enlarged view of main wheel and main spring barrel showing themannery of mounting the ring wheel; Fig. 6 is a view similar to Fig. 2with the lever setting arrangement removed; Fig. 7 shows connectionsbetween the main spring barrel, main wheel and indicator attachment toindicator hand wheel; Fig. 8 is an enlarged section of the planetarysystem; and Fig. 9 is a cross section of Fig. 8.

with. the safety barrel 9, which is provided The main wheel 10 ismount-y with teeth 9a. ed loosely upon the 'barrel arbor 8 and mesheswith the gear wheel 11.

The letter A indicates the lower plate of the' watch and B the upperplate, taking the dialV face as the lower part of the watch when thewatch is open from behind to expose the works.

The planetary system is in the form of a unit made up of the followingparts: As above stated the gear wheel 11 is engaged by the main wheel 10and rigidly connected with said wheel 11 is the sun gear 21. Therotating arbor 15 has the journal portion 15l which passes through theWheel 11 and pinion 21 and is jouprnaled in the upper plate B asindicated in Fig. 7. At the opposite end of the arbor 15 is formed thepinion 16. VA casing 22 has the openingy through which the arbor 15passes, said opening being as large as the pinion 16 so as tovpermit ofthe withdrawal of the arbor together.v

with the pinion from said casing. The casing 22 has the gear wheel 14connected' or in the rotating arbor 15. The teeth of the planet gear 19mesh with they sun gears 20 and 21. By forming the planet gear 19double-convex I lobtain a stronger construe# tion and am enabled tolocate said gear A planet gear 19 which nearer the center, therebyenablingv mev make an attachment takin and also enabling me to eige theteeth of the sun gears 20 and 21 than would be the case if said planetlgear were fiat on the inside. By having the stud 18 integral with theplanet gear 19 I dispense with the necessity of securing a stud orvbearing into the said planet gear which makes it possible to employ asmaller at-l Furthermore by recessing ,the gear wheel 11 for thereception of the sun tachment.

gear 21 I save space and am enabled to make a more compact device.

I have illustrated my invention in connection with a watch of standardconstruction' in which 23 is a set lever and 24 is the shifting cam. Theshifting cam is fulcrumed on the screw 24a and the screw 27 passes upthrough the top plate B into the bottoni plate A to hold said platestogether. In order to connect up with the teeth 9 of the main springbarrel I form a hub or boss 12 in the bottom plate A around the screws24* and 27, so as not to disturb the original construction of the watch.Around this boss up less roorn', ar more easily tor wheel 31 mounted onthe pivot 32 in the cap 33. The indicator hand 34 is secured to theindicator wheel 31. During the winding, motion is imparted to the pinion2, through the crown wheel 4 and through the ratchet 5 rigidly connectedwith the main 'spring'. barrel 9.

The teeth of the main spring barrel 9 impart motion to the wheel 12 andthroughthe teeth 13 and the gear wheel 14 the rotation of the gear wheel14 `.carries with it the sun gear 20 and the planetary pinion 19 isrotated, carrying with it arbor 15, said pinion 19 traveling in the,teeth ofv the sun gear 21 of the gear wheel 11, which is relativelystationary by yvirtue of its connection with the main wheel The rotationof the arbor 15 through the pinion 16 imparts rotary movement throughthe intermediate train to the indicator hand 34, returning the same toZero.

A When the watch is running the gear wheel 14 and sun gear 2O remainstationary by virtue of the wheel 14 meshing with the pinion 13 which isheld from rotating by the main spring barrel, being connected with the1-.ratchet wheel 5 held from rotating by the Aordinary pawl. The mainwheel 10 im-v parts rotation tothe gear wheel 11 and through theconnections described the planet gear 19 is rotated and its teethengaging the stationary sun gear 20 it rotates about said pinion,carrying with it the arbor 15 whereby a reverse movement is imparted tosaid arbor and pinion 16 and the indicator hand 34 which moves over thedial to indicate the amount the watch has run down. f

By the employment of the plate 25 for holding down the shifting cam 24 Iam enabled to locate the pinion 16 directly below =-said shifting camwhere the screw was originally located for holding said shifting caminposition. -I am thus enabled to lo* cate the indicator mechanism inthe watch without changing the location of the shift- .fling cam whichwould mean a change in construction of the watch movement.

.While I have referred to pinions 20 and 21fasV sun-gears it is to beunderstood 'that they only act as such alternately.

` The safety spring-barrel has been em- I l ployed in' the present casebut it is apparent that .the device will work equally well withtheordinary main-spring barrel.
